Its quite possible to easily emulate certain "missing" pedals with a few quick adjustments and numerous threads that explain exactly how to dial in some of those settings. Just tweak, then save the block in Axe-Edit naming it whatever you what, and there you go, new drive blocks added.
Keep in mind as well that about a good 95% of dirt pedals on the market these days are all just slight tweaks, if not out and out copies of existing circuits. Someone swaps out a resistor value for a little less bass, comes up with a cool name and flash graphics and its a TGP darling for a few months, until it becomes apparent that its actually a $30 made in China clone pedal that was being rehoused with a huge market lol, just keeps happening again and again.
Whats so cool with Fractal is you've got the power to adjust things like the high and low cut of a given pedal, change tranny types, add in a little dry signal, etc etc
Its not to say that every pedal can be exactly replicated, I still have a few favorite stomps like a germaniaum fuzz myself, but the drive block is pretty good overall
