Dilemma transfer from bucket to carboy or carboy to bucket

Well this is a pickle I didn't intend on.

Right now I have a melomel that's sat in a primary bucket for a month. I need to transfer it to secondary and begin its second fruit addition which it will sit on for 1 month.

I also have a cider which has sat in secondary carboy for a month.

My original plan was this

Transfer the cider to keg and begin carbonating, clean the carboy and transfer the melomel over to that.

I've never used a bucket for secondary, I am unsure if the melomel would be fine in an 8gal bucket for a month or not. I know it'd likely make the fruit addition easier. This normally wouldn't be a problem as I can go to LHBS, however they're closed mondays and I need to move this melomel.

if it'll be fine in the bucket for a month I'd rather do that vs moving the cider over to keg which honestly needs more time to clear. Any help would be greatly appreciated.
