Sorry to be confusing. Yes, they can eat themselves to death, but if your only choice is to put them in the tank you could do it. Refugium is much better. If the guppies or ghost shrimp can scavenge in the refugium, you shouldn't need to feed them. BUT, the purpose of gutloading is to provide enhanced nutrition to your angler. It's not absolutely necessary, but it's a good idea.

I've read that it can take a few hours to a week to acclimate guppies or mollies to salt water. If the fish or shrimp are in good health when you get them, you may be successful using a drip line over 4-6 hours. I'd get a bunch of plain feeder ghost shrimp or guppies in decent health and give it a try. If your LFS has brackish tanks, they may even have brackish acclimated guppies, mollies or ghost shrimp (for feeding store fish) which are even easier to acclimate to full salinity. I acclimated my molly and ghost shrimp quite a while ago, but I think I did it over several hours, definitely not a week.
When I did wean my anglers to live food, I found that strips of ocean nutrition gel cubes (I varied the types) really enhanced the growth rate and colors. I'd feed a thawed pieced I cut off a cube from a piece of stiff fishing line or a bamboo skewer (sharp end blunted). I could feed my larger adult anglers half a cube at a time.
