There's a lot more to it than that.
First, you have to find a snare sample that's appropriate, and that fits in the context of the song, and that doesn't clash with the original snare in the overhead tracks. I may have to spend at least an hour searching through my archives to find something appropriate.
Then, if you don't want it to sound like a cheap drum machine ... you'll want to select multi-samples; i.e. a few random hard hits, and in the event there's some dynamics involved, you'll also want to select a few medium to soft. This might take another 1/2 to 1 hour, depending.
Then you're going to want to go through and make sure the replacement hits are phase-aligned with the overheads ... or else your snare will sound thin and cheap; thus negating all benefits of replacing the snare in the first place. This part could take at least 2 hours, because in most cases, you're going to have to go through each and every hit, manually, and check it. It's not just a case of lining up one track and you're done, because there is likely to be some drift with the program (where drumagag doesn't respond as fast).
I am assuming that, for this task, you would be willing to play a party for one of my over-seas friends who might be local to you ? Or that you would be able to provide them with a voucher for 5-6 hours of free tracking or mixing time?
