Replacing halogen transformers to led

[headintheclouds]

Hi

I trying to replace my halogen transformers with LED equivalent. I have 4 spotlights and they have there own transformer. 3 of the transformers I can get to but I can’t get to the last transformer because it’s in an impossible area to get to I think the previous owner has placed the transformer behind the joist to were the light is and the wire runs underneath the joist and above plyboard. So only only solution would be to rip the ceiling down or rip the floorboards up. Is it possible to daisy chain an existing halogen transformer to an LED transformer? Is there any other ideas you could recommend?

Thanks
