Ok so commitee said that my idea for running something that wasn't TL as part of BathLARP was quite understandably taking the piss as I was trying to minimise the effort I needed to input to run an entirely different systemw ithout making my own LARP.
That being said I can't get the idea of running a high threat, low NPC, survival based LARP out of my head. I'm looking to use "TL light" rules in something similar to the a town from the KoE transported to another plane of existence with no way back. Key themes are: limited resources, low/nil NPC power, slow character progression and encouraged cahracter retirement at higher power levels. What do people think? I might post what I'm got as rough notes tomorrow, we'll see.
