This may be a dumb question,

Many cheap to fairly cheap gunstocks are Sycamore. It doesn't stain that well or has very little figure in the grain. I'm talking about those stocks like are on midrange springers and even cheaper guns like you would buy for your kids' second rifle. 
I ran across a pic of an air rifle on the internet the other day that looked kinda like it had been painted almost black and had creme colored checkering. I thought it looked kinda neat. 
A coat of hard epoxy paint wouldn't add that much weight. If weight is an issue then drill out the butt of the gun a little. Cheap guns aren't built with much balance in mind anyway.
Just a thought.
 
"azuaro"You can bring those "cheap wood no grain stocks" to life by sealing the stock in its natural state (no stain) and then by using gel stain and other tricks to simulate the wood and the grain you desire...With practice you can do marvelous things...The doors at my summer home are made of composite because of harsh -40 F colds, ice and snow in the winters, they are painted on the exterior but the finish on the inside matches the wood color and grain of the rest of the indoor doors made from solid walnut.

Nowadays Hydrographics with wooden grains and knurls are a good alternative and can be applied to synthetic stocks, then you can apply clear coat and the gun will fool anyone while having the best of both worlds: Synthetic stock with a very high end finish...A friend of mine did his wooden shotgun stock with a very high end look of Circassian knurl walnut...it fools the most discriminant eye!...Those graphics look very nice if done right. 

I like synthetics and specially black in military weapons, bull pups etc. as used by FX and other air gun companies, it is just the Sporter type of gun or very high end guns that I don't like in synthetics, but this is me...I belong to an older generation that is now seen as old fashioned and that is OK too.

I agree with most all of that, but I don't like synthetics on anything. Good wood on a gun can be art to me. Bad wood on a gun ruins everything about even the most expensive and accurate action and barrel. I am maybe too much of a traditionalist and set in my ways. I'm almost 63 and becoming a crusty old man. Geeez.
 
 Diana does that. Paint, dye, stain, plastic over coat.
"Premium version, based on our model 48. Walnut coloured beechwood Monte-Carlo type-stock, fine cut
checkering on the pistol grip and forend."
VERY high gloss. Does indeed look a bit like walnut. so IF you like it it can be done. I believe their 2015 catalog shows a few examples.
