The specs for your rifle are 180-degrees opposite what I'd want in a mountain rifle, just further proof that what is perfect for 1 man is a non-starter for another man.
If I was going to build a mountain rifle on the cheap, I think that I'd do another faux-Ti; 700 CM action, 700 Ti stock, and 700 MR or Ti barrel in CM or SS. Although I don't really care for the geometry of the 700 Ti stock, it is the best light-weight stock for the $$. I've done 2 of them in 260 and 308. Mounted with Warne bases/rings and Sightron SII 3-9x42s they are both light and handy. I'd probably do a couple more, 22-250 and 243, if I could find stainless MR contour barrels in 223, to get the 1-12" ROT, and 243.
