Sure, but this might win you a couple of years max. Homebrew's "Support Tiers" page, which I linked, also addresses OCLP users, going so far as to specify a minimum Intel architecture. So, even if you use OCLP to allow support for newer OS versions, eventually your CPU architecture will be too old and you're back in Tier 3.
Also, the writing is on the wall: Ultimately, Homebrew will be ARM-only, once Apple's legacy support becomes ARM-only. At which point it's game-over for Intel Macs.
Homebrew solves the "availability of software" problem in the Mac ecosystem, but it does not solve the "Need to stay on the new hardware treadmill" problem.
