The TileCache layer name does not need to have any relation to the
GeoServer layer name. So, your config could look like this:

[mytclayer]
type=WMSLayer
layers=my:geo:server:layer
...

This way, the cache directory would be based on 'mytclayer', and you
would be requesting data from GeoServer as 'my:geo:server:layer'.

Will this solve your problem?
