This layout looks similar to one my oldest daughter is using. I drilled out the removable plastic cable stop to make it a cable guide. I like running full length housing. You should be able to redirect the cables from the bottom cover plate. Not sure if you can access the seat tube though.
Does your frame have the access door under the bottom bracket? What is the purpose of this door? It looks like there should be access to the seat tube since that's where the front derailleur thread comes out of.
