Is there a way to factor out the bash profiles?

A portable application shall not rely on any user modifying their bash environment.

If the intention is to provide a user enrionment for interactive analysis, then consider adding activate.sh and deactivate.sh for entering and leaving the environment?

If the intention is to provide a single point of entry then perhaps migrate some of the settings to a config file that can be parsed and loaded easily.
