Crosman/Benjamin stock swap ?

I'm toying with the idea of swapping the stock out of my Crosman F4. As I search the internet, it seems that no one makes an aftermarket stock for any of the hundreds of thousands of Crosman/Benjamin air rifles that have been sold. It looks like the Remington (Crosman) Summit stock is a good fit (and a decent looking stock I might add) but availability of the stock seems rare. Does anyone know of any other options for this or am I just stuck with what I have?
 
I played with this kind of swap idea quite a bit a few years ago. Traded stocks between an F4 and a Benjamin Titan, then bought another F4 with a synthetic Monte Carlo stock and worked that stock into the swap mix. So, no, I never did find a stock-only aftermarket part made specifically for these guns. I did toy with the idea of buying a Crosman Vantage or Optimus, whichever was on sale for lowest cost, so I'd have a wood stock to swap with as well. Never did it but still am convinced it would present no issues in accepting an F4 action - or any other Crosman/Benjamin NP or Spring action. My recollection is that the NP2 guns did not have the same stock screw placements and were not suited to the experiment.
 
Thanks guys, your responses kind of sum up what I have found so far. I actually don't mind the thumb-hole stock on the F4, from an ergonomic standpoint it fits my preference pretty well. But I am a "tinkerer," and I was looking for a little side-project to refinish a decent wood stock with my own personal touch. I've read (old) posts of guys that bought the Remington Summit stock from Crosman shipped for $27 or so, and honestly from the photos it is one of the better "cheap" stocks that I have seen that actually have a decent defined natural wood-grained pattern to them. But, it's not a deal-breaker if I can't locate one. I really do like my F4 because I can lay dime-sized groups at 30 yards with it. But in terms of options, I suppose there is only so much to expect out of a sub-$100 platform (not counting the aftermarket optics lol).
