Tough call,
I'm pretty sure the triggers would fit in the hole in the proper position with only a minor amount of in-letting or wood removal most likely in front.
The problem might be with the stalkers trigger guard being big enough.
I've got kind of the same issue going on with a TC New Englander. I know the TC double triggers will fit with minor work, but I have to change and inlet the TG,, also kind of a minor issue.
I'm just trying to justify the expense, even ebay parts will run me $50-60.
