Half-fixie bionx?

So over the months since getting my Bionx it seems others have said before me, I am out performing my big ring. As I've gotten in better shape again ,what I have come to love about bionx is the 'takeoff' assist or just getting up to speed before I get my own momentum going. Previously I did a lot of searching on how to get bionx to assist past the normal 20mph , since then I've become totally content with it's inherent limits .
Ok, Bionx can assist with 'takeoff'. You know, like in the time trials where the coach runs pushing the rider till he takes off? Most People who ask the famous 'how fast' question would love for the coach to just push forever. Anyways ,now 'up to speed' isn't up to par :( with my new legs. Past 20 on a flat I end up pedaling like an eggbeater to maintain. So , I started thinking of swapping cogs ,then I thought of the last time I even used the front derailleur . Yep , just then i figured I could shave a good pound off,stop some rattling and chainsuck all in 1 fell swoop. Ordered a 48 tooth ring ,plan on removing both babyrings ,shifter and cable. May go with a downhill tensioner or plastic chain guard ring. Any suggestion ?
