Just move the whole thing down. If you've got plenty of wood below. Then lock will be ok, front lock bolt will still work.
Lay out is started with the barrel, then the lock, trigger, etc.
Angling locks, leaving out lock bolts, shortening sear arms shouldn't be necessary, or done.
Bottom line, if you can't make the layout work, get a new piece of wood. It's the cheapest part.
