I don't think so. The tray siphon is designed to maintain a water flow
from the bottom (where the hypo sits) in a flat tray. IMHO a much better
way would be to leave the film in the tank and have the water flow in from
the center, pushing the hypo up and out.

If you wanted to get technical, you could rig up a hose from the faucet
into the spindle, less technical, use a funnel, really simple aim the
water into it.

Really, one can be successful in processing film and still take many
shortcuts (although there are some dangers in doing so). If you have
a deep enough tray to fully submerge a reel, maintain a brisk flow of
water, and leave the film on the Jobo reel it does work (I've tried
it). It is not elegant, convenient or necessarily guaranteed in all
circumstances. Under field conditions, it can work.

If you try it be sure to consider how stable a "deep enough" tray is,
and what are the consequences of dropping it (but then, you may not be
as clumsy as I am).
