Ish... math wise yes, viscosity wise not so easy. You can try it and see if you like the desired result, or just buy a $3 bottle.
There was somewhere on here ( RCTech, not this thread) that had a link to a site that would tell you how to mix what with what to get a desired weight. Try google. Thats about all I can offer.
