Definitely! The Raritan PH SuperFlush is the current version of their PHII, which has been the top rated manual toilet since Raritan introduced it in 1983. I've only been able to find one retailer who has the "conversion" (everything but the bowl, seat and lid) and their price is very reasonable:

Vented loops can be that low on a powerboat because powerboats don't heel, but to put them the required 6-8" above waterline on a sailboat AT ANY ANGLE OF HEEL, not just when the boat is at rest, puts 'em 2-3 FEET above the bowl. And he's gonna need one in the intake too...and it also needs to be just as high. That one does not go between thru-hull and the pump...it needs to be between the pump and bowl, which requires replacing the short piece of hose the toilet mfr uses with two that are long enough to connect to a vented loop where it belongs. (see attached photos)
Ronco Plastics is your best source for a tank. They make TOP quality thick-walled water and waste tanks for a very reasonable price and have more than 400 shapes and sizes, over 100 of which are non-rectangular, and they install fittings in the sizes and locations specified by the customer when they make the tank. There are retailers who sell Ronco tanks, but Ronco sells direct for a much lower price...and they're great to work with. their marine tanks catalog is here

et me say right here that this is a low budget project until we have all systems working and decide whether the boat is worth putting any real money into.
With that in mind I have a suggestion: pull the toilet, tank and all the related plumbing out...buy a portapotty to use (about $50 at Walmart) IF you can even be on the boat long enough each time you're aboard to need toilet facilities while you figure out what it's gonna cost to take care of everything else on the boat that needs to be repaired/replaced and get the boat cleaned up. Then you can decide whether it's worth putting any real money into...if not, install a 5 gal. "MSD" portapotty (marine portapotty that has the fittings for pumpout line and vent line and sell it as-is.
Btw...what is this boat and how big is it?
