Yeah, but Richter looks cool and anime-ish. So i used him because I like that look
I actually agree with you about them being for the most part interchangeable... I mean let's face it, Richter looks just like Simon from Castlevania 4, except with an Anime style. And the initial simon from castlevania 1 and trevor looked EXACTLY the same basically. But in this case, it still feels like playing Richter because of the sounds and because by now people are so used to him being in so many games.
But my advice is if people don't like this, let someone edit Richter's sprite in a way to make him look more like Simon and send it to you. If you like it you can use it, if not tough for them. So far the sprites I have seen people offer for Simon here haven't looked nearly as cool as Richter's does. You could also use Simon from the x68000 version (not the faggot red hair version... the normal one. dear god, talk about gay), but he would need some touching up.
Again, since people have issues with this let them contribute (since you are happy with Richter as is), and then you can decide if you like their work or not. In all honesty, a small head edit, and some minor changes to Richter would make him look a LOT like Simon, but sadly no one here has even tried to do it.
As for PM'ing I use MSN, so if you want to chat feel free to u2u me your sn and I can write you on there.
