Sounds like a great chance to experiment Doland ; ^ ) As you say, going with less rake will increase trail which may or may not be a bad thing, depending on how you like the current handling of the bike. The change will not be huge, for instance if your head tube is 73 degree it will take you from a current ~5.2cm of trail to ~5.7cm - still pretty much average for current racing bikes, so steering shouldn't be drastically slower. And who knows, you might even like the added stability.

Of course you could also experiment with re-raking your old fork, assuming it's still structurally sound and you don't care about potentially messing up the paint. I'll probably get in trouble for saying this, but a 2x4, a rubber mallet, and a tape measure are all you need.
