I actually agree with you Pedro, although Billy had the potential to be a main stay, its already to late, and Capcom probably doesn't care for it. BUT I actually feel the same about Rebecca, she was a supporting character in RE 1 and was used in RE Ø only to back up the story that was told in RE. and she hasn't been used since, despite her appearance in The Mercs. So, if Rebecca were to get another role in the series, I would think Billy should deserve the same.

Capcom discovered that to give Barry his own game, they would need a console that will not be invented for another 20 years, just to do his awesome action beard justice. Thats why Gaiden was so terrible. The beard just doesn't work on 8 bit.

Has all say, like part of them are in the Mercenaries game, hope that Carlos (maybe a dream at this time already) can Capcom say somethin about him, or let him appear like a Mercenarie (ohh wait, in RE3 is already appear), I'm scrwed :(

Oh Mercs in RE3, good times right there.

I would love for Carlos and Billy to be in a Mercaneries game, maybe RE6 i'm hoping, I have more faith on that now seeing the seemingly random inclusion of Barry and Rebecca in Reunion.

God listen to you bro. Yeah very good old times, perphaps the best, for that time, sure, anyway, like you say, if Barry and Rebecca appears in 5, why not Carlos and Billy, besides, RE3 - RE6, 3 years exactly, the perfect moment for Carlos at least.
