Pump the bearings full of grease immediately before launching?

Hmm - no clue as to the boat or trailer type or if you're launching into salt or fresh water ... nor for that matter how far you have journeyed with the trailer to get the bearings hot to start with ...
The obvious answer is to let the hub cool before putting it in the water ... you could possibly accelerate this process by splashing them with water ... in a controlled manner ...

You can get pressurised bearings that seek to solve the problem.
However, there is only one thing better than waiting for an hour and pumping a bit of grease in prior to launch
and that is use a crane

Bad idea to immerse road trailers (Illegal in some counties I believe) it's not only the bearings that suffer.
If you must then let the hubs cool first. Pump full of grease? but the hubs should not be over greased (I overpacked some wheel bearings once and the grease almost turned to oil.)
If they are still available fit "bearing savers "
Otherwise yes pump some grease in but after immersion and before taking on the road strip, clean and repack the bearings with fresh grease.

Ye Gods, it's even on the RYA powerboat Syllabus -
when arriving at a site, allow the bearings to cool before immersing the trailer.
If you really are that impatient, get a two part trailer/trolley arrangement

Oi! ... I assume you mean that reply to Kalpesh and not me ... you don't even want to look at putting my trailer in the water with the boat on ... you'll never see it again (the trailer ... the boat will float!)

Fit the oil-seals the "wrong" way round & they won't allow the ingress. Don't pack them too full of grease & they won't fling it all over the place either.

Get a "breakback" trailer and you don't need to get the wheels in the water. Magic!

I would heartily endorse that, when I used to tow a Devon Yawl I had all sorts of bearing troubles, including a wheel bearing fire on the M5. Once I got a breakback and kept the wheels out of the water no further bother.

Most trailer manufacturers do breakbacks as well has fixed spine trailers. Try whichever is nearest to you?

If the hubs are that hot, take a look to make certain the bearings are not overtightened (or with too much pre-load if tapered). Also check that seals are intact and correctly fitted. You shouldn't be 'losing' grease to the extent you seem to be. As above, VicS, use the correct grease and don't overfill. Nearly all bearing troubles are caused by incorrect fitting and/or poor maintenance.
