From my experience. I'd start with a small batch (enough for one full liberal coat) of the blo recipe you listed. Put that on and let it soak in for a good 15mins, then wipe off. You'll find that the oil keeps rising, so keep coming back to it and wipe again until you don't see it rise anymore. Then let that cure fully. After that I'd just carry on with homebrew wipe on poly for the remainder coats. This would be the fastest way as once that first coat of blo has soaked in, the subsequent layers do take a while to cure, which is why I'd then just take the blo out if the equation.
YMMV as different climates play a big part, so maybe try it on scrap first to get the vibe of the thing.
