Sample based stuff isn't your best bet for synth stuff, although Trilogy is pretty good. But if you want to mangle the sounds and modulate them lots of ways, it's a limited approach. There are a few free Reaktor ensembles I think but I don't believe Monark is in there (which is the only one specifically made to emulate Moog).
The Bass Station is pretty good but I always considered Novation to be closer to the Roland sound than to the Moog. Only familiar with the V Station though and that's pretty dated, sound wise.
Z3TA+ is pretty versatile which means you can at least set it up with most of the right parameters to sound like a Mini might. Just google the properties of the specific Moog you're going for. The 24dB/Oct LPF is kind of a given but the Mini's envelopes were also specific, as is the configuration of oscillators (3, but you could switch the third to LFO because otherwise you had none), the "lowest note" priority, etc.
