for a bobcat yes it is possible tho not perhaps practicable, involves pump, plumbing, electrics etc. and pricey!
my service guys got a tad nervous when i asked them this same question inc pricing (about 10k as a rough guide locally)...
bobcat do not use 5 hoses coincidentally cb, though I understand the hoses used are a different diameter to the std flow hoses even though the couplers are same same.
a better question to ask is what do you really need hiflo for? perhaps if its for some wishlist of attachments in the future it might be better to use a std flow in the interim and change out to a hiflo if and when you prove a need.
remember what the large frame bobcats spit out on std flow which is slightly more than what a S205 hiflo will give you. maybe a large frame wil suffice unless you desire the full monty.
i can safely report a soil conditioner works far better in hiflo on a S185 than on std flow but only cause the drum spins faster and thereby seems to stall less.
my std flow 72" soil conditioner is rated to slightly above medium frame hiflo specs and the 7 pin detects the hiflo option on the 185 and automatically engages hiflo for you.
