Most class features have magic item equivalents. It'll take a lot of reading to figure out the cost of things but the gold costs as far as I've seen are pretty balanced.
maybe just go with the wealth by level table. Call gold points and call magic items abilities that go into "ability slots", slotless items become slotless abilities. there are items for feats. magic weapon price can simulate BAB.
It sounds what you're looking for is a different game all together though. The bestiary and chalenge rating of monsters in it was designed with player character levels at it's base. It's almost as important a mechanic as the "roll a 20 sided die + static modifier and compare it to a set number" mechanic
