I would spend FAR more on K&C if they did unpainted, injection molded plastic.
I love the look of K&C, but they are very fragile and ever more costly. When I receive damaged or mis-painted figures the fun is over before it started.
Injection molded plastic, if both rigid enough to hold a paint job yet flexible enough to not break if dropped would be ideal.
BMC Iwo Jima seems to have done OK. I would hope for somewhat more flexible plastic than BMC uses and better detail. Hard, brittle plastic is not something I'd be interested in, nor would those who would let children play with the unpainted plastics. Detailed rifles and bayonets in hard plastic are not going to do well (breakage, durability, liability) if there is hope of an expanding, overlapping market with kids.
If a less costly line is created, I can't imagine why it wouldn't serve a secondary purpose as an entry point for kids/future high dollar value purchasers into the hobby.
How many collectors here started with Marx and Airfix?
On the brass tacks side, I have a dim view of the future of the dollar. If K&C sticks to the previous production system I can easily imagine figures at $50 each in less than a few years.
If you look at the movement of the USDX dollar index over the past 10 years, I'm surprised they aren't even more than they are selling for now.
Helicopter Ben is going to break the dollar and everything produced elsewhere (especially China) is going to become shockingly expensive, IMO.
