You want to access the tiles in another projection? Hmmm, it should work with a configuration like this:

layers:
  cache1:
    sources: [cache1]
  cache2:
    sources: [cache2]

caches:
  cache1:
    sources: [tilesource]
    grids: [GLOBAL_MERCATOR]
  cache2:
    sources: [wmssource]
    grids: [GLOBAL_GEODETIC]

sources:
  tilesource:
    ...
  wmssource:
   req:
    url: http://localhost:8080/service?
    layers: cache1

That should work out of the box if you use WMS.
