A thought -- if you're going Peralta TH to Canyon Lake northbound, my personal preference would be either Peralta Tr or Terrapin Tr to Dutchman #104 - and go right (east) at the junction (off towards Charlebois).
If on Peralta then you'd need to go up Black Top Mesa Pass. If on Terrapin, most of your climbing is done by the time you get to Dutchman, and you're then descending toward middle LaBarge next to Bluff Spring Mtn Canyon.
I would then take Cavalry Traill #239 and link up with the northern half of Boulder Canyon #103 (this bypasses the most annoying parts of that canyon in my opinion). The views along Cavalry are well worth the short amount of time you are in the lower part of Boulder Canyon. You're only something like 1.5 mi to the confluence with 2nd water #236 by the time you pop out the western end of Cavalry. From there going north there are maybe 5-6 of those frequent crossing points and only two of them are actually annoying to hobble over. Also #103 should not be overgrown again until late April. I find the walking to be surprisingly quick through that section.
I've been doing some multi-day trips lately along a similar route and have really been enjoying the views along Cavalry - not to be missed!
But if you are hell bent on avoiding Boulder Canyon then follow Joe's advice
