How much RAM is this going to use?

Good question, I'd be aiming for a 64 bit compiler with ~4 GB max memory
usage, the ASN.1 compiler I made with pegged stayed well below 2 GB with
1000 lines of BNF->PEG rules unless I had 700+ lines of code to parse
(which check every OR possibility at 3 levels deep for the longest
matching solution).
It's very efficient when you generate the grammar in a separate D file
and make good use the garbage collector rather than mixin the grammar
directly.
