Having an engine with the same system, no, it won't work.

We've done street tests and dynos, and with the short runners open at low rpms, you lose a whole lot of power.

The runners don't just provide volume, the tuning of the long runners is optimized for torque. Shortcutting that will lose you said torque.

What you may want is to hook something like an aftermarket "VTEC solenoid", which allows you to select the activation rpm for the secondary runners. Set it a bit lower (maybe 4000 rpm), but not too low. Dyno data for your specific engine should tell you where the runners always open and runners always closed graphs intersect, and where it would be most useful to open them.
