I like this as well. I've come up with several fun, creative encounters simply because I had a weird mini and no other way to use it.You know, I bought quite a few of the random minis, mainly because I liked getting oddball ones that forced me to be creative in order to use them.
Heck, i'd love to see WotC go all out and creep into Dwarven Forge territory. If anybody could do it well, and cheap, it would be Hasbro. They could release collectible sets (or preferably non-collectible) that coincides with adventures modules being released.
When are we going to get a ******* ABOLETH?
A classic D&D monster i would love to have. Reaper made an awesome metal one, but i'll be damned if i'm going to buy for that expensive 5 pound thing and then have to paint it.
