What are your current lights?
What are they powered by? Internal batteries that charge via USB or rechargeable batteries (AA/AAA/etc)?
Do you want more lumens out front, out back, or both?
All with inbuilt rechargeable batteries. The rear flash is probably ok. But I’d just rather have a more powerful system, ideally one with a shared battery. Is this too much to ask? (Yes, clearly).
I would just let go of your desire to have it switch across bikes. Put a dynamo on the commuter and use regular rechargeables on other bikes
