I think we totally understand, after all we have all been there (people like me more recently, others...well few decades I suppose) and precaution is a very good thing.
As far as dangers go Iīd say as long as you donīt pull any stunts and damage the PUs directly or damage the wires somehow I think you are save. I am not aware of any way you can damage the PUs by just repositioning the ends of the wires.
However you should watch that you donīt drip solder into the switch and do not heat the pots for extensive periods of time (for multiple minutes I think). If the solder wonīt melt, donīt just continue heating the pot, add some fresh solder so get a better heat transfer.
Thatīs all from the top of my head.
