We would, however our intention is to make a combo character for Galactaknight. I haven't Seen Dark Metaknight though, so I don't know what sort of moves he has that might be available, but depending on how different he plays, we may borrow a move or two. It all depends. But Galactaknight is being conceived right now.
Funny you should mention, I have been working on fusing Metaknught and Dark Metaknight! So far I've gotten his Dark Meta's S-Smash done. All I really need to do now is finish his D-Air and S-Special, then post to the vault, so you could take a look and evaluate (I know you've concived GalactaKnight, but looking would still be good).
Ness and Ninten (The issue here is deciding how to make him play, since really most of the PSI powers that Ness uses are powers he didn't use, Paula did however. So I was considering her at one point since Ninten's powers from Mother 1 (Earthbound 0) were as limited as Ness'. So we'll see basically, but Ninten is definately considered)
As for Ness + Ninten, I would imagine Ninten having stronger PSI attacks (PK Flash, Fire, etc), but weaker physical attacks (Bat swing, kick, etc), while Ness would be more balanced compared to Ninten. Alternatively, a user named Alses made a moveset for Ness that was a hybrid of his and PM Lucas' moveset, so there's that, too.
Pit and Dark Pit (We just need someone to make Dark Pit from Smash 4. At this point in time we have too much on our plate to want to make a Smash 4 Dark Pit moveset. So we're hoping by the time we finish some of our creations, Smash 4 movesets will become more of a common thing on the vault).
It should be worth noting that someone did make a DarkPit moveset... sort of. It is more based on the PM Pit moveset, but it does feature some of Sm4sh DP's traits (different arrow, stronger attacks, etc) so you might want to check it out.
http://forums.kc-mm.com/Gallery/BrawlView.php?ByUserID=39746&Moderated=AllI've been asked to look at the Isaacs, I just haven't aha I'm busy with my stages right now is all. But I intend to, he's a very highly demanded character, so I'm sure he's got something about him that's appealing.
YES. I would certainly recommend either of the Isaacs (once you're finished with stages, of course). However, they do have issues (one gets stuck with Down B in air, and the other can use Up B forever with no Psynergy points). I'd still reccomend them, though.
We're all doing our best
Amazingly, most of your suggestions are already in the cards so... we have preemptively considered them
I see... so perhaps, I'm a clairvoyant?
Also, I feel very honored talking with you. You're like, my hero or something.
