I set out today to try and solve the grease problem on the hg15 and I think I may have done it with a little m4 nipple some silicone tube and a syringe to inject the grease which I plan on warming up first so it's a little more liquid. I will report back tomorrow when I give it a go.

I use this method all the time on hard to reach areas, even with 6mm nipples. Don't mess around with a syringe buy a small grease gun. Then put standard 6mm nipple on one end of pipe with threads inside the pipe and 4mm nipple on other end with nipple inside the pipe so can screw into bearing.

Then just connect 6mm to grease gun as normal. You'll need to wire the pipe to the nipples else the pressure blows them off.
