He's a famous enough character among civilians, that you can justify taking that risk in putting money on a movie with him as protagonist. To the extent that any supervillain had a shot of getting their movie, Joker would be in the front of the line. In the case of Doctor Doom, you have a character who has never really crossed over in any big way before. He's well known and famous among superhero comics fans and Marvel fans, but ultimately movies are meant for the civilians who don't know any of that.
2) You need a leading man to play Doom. Look at the actors who have played Joker in live-action (Nicholson, Ledger, Leto, Phoenix). Four of those actors at the time of casting were Oscar winners or Oscar nominees (I know Leto sunk his reputation a bit when Suicide Squad came out but in the lead-up his casting was praised and highly anticipated) who had experience headlining their own movies. Part of the reason why Joker got to headline his own movie was that a long time before, WB set a tradition of casting major leading man actors as the bad guy (in the case of Heath Ledger, they cast an actor who was a potential choice for Bruce Wayne in the first movie, which further heightened the duality of Batman and Joker, and also helped sell Joker as Batman's greatest villain since they cast an actor of equal stature as the leading man in that role). To make a Doctor Doom movie, you need to cast a leading man actor who can carry a movie. To help make the case of Doctor Doom as Marvel's biggest villain you need an actor who has equal stature to RDJ and others...someone like DiCaprio or Adam Driver.
That leads us of course to
3) Doctor Doom is a character who spends all his screentime behind a face-covering mask. So whoever you cast in that role is going to be asked to play a character whose face (which is basically the essential tool for any actor) is covered for a significant stretch of the screen. This is not an uncommon problem in superhero movies (consider how often Spider-Man removes his mask in the movies as opposed to the comics before the movies) but in the case of Doom, he's scarred horribly and the mask covers that scarring so you can't really dodge this issue. This makes it harder than Joker (who you basically need to cover with white face paint and green hair but that still allows the actor full range of facial features to perform). You can get around it by doing a movie of Doom based on his origin (where he spends most of the first act with his face, and then the second acts until his rise to power behind the mask). Or you know if you adapt Secret Wars and the finale has Doom's face repaired. But in general you are going to have to ask an actor to carry a movie with a mask covering his face the whole way through.
Of the lot, I think 2) and 3) are the biggest hurdles to making a Doom movie. Marvel made a hit movie out of Guardians of the Galaxy so I don't think making a movie on a villain even one a little unfamiliar is a hard thing for them. So 1) is not a problem for them.
The biggest issue is the mask. There are some cases of actors doing incredible performances with the faces covered...like Edward Norton in Kingdom of Heaven (which has to be the reference since that was an emotional and dramatic and interior performance), you also have old fashioned monster movie performances like Boris Karloff in Frankenstein where you see an actor selling emotion under heavy make-up and covering, Gary Oldman's Mason Vergere in HANNIBAL (a bad movie overall) is another example of an actor under layers of makeup and scarred face doing a great performance. But these instances are usually supporting performances or villains. That applies also to Darth Vader who many people point to but Vader himself is not the protagonist of any of the individual movies he appears in. Lucas does manage to get emotion out of the body language and fight choreography (played by two different actors - David Prowse and Bob Anderson) and from the great VO by James Earl Jones, but with Vader the idea is that he's more machine than man, and that he's surpressing his humanity, whereas Victor is always Doom with or without mask and armor.
Because of the mask, it's going to be hard to attract the attention of a DiCaprio or a Driver. Not to mention those two will want a big payday out of a role like this.
