[TowerTalk] Balun with parallel connectors?

Hi, gang,
I'm thinking about building two chokes that can be inserted at/near antennas or at/near my radios. I plan to use rg-400 and an FT-240-31 core built inside a plastic 4-inch utility box from the local big box store.

To maximize flexibility, and because I often use RG-6/RG-11 in addition to the usual 50-ohm cables, I'm wondering if I can get away with building the chokes with chassis-mount "F" connectors and the usual SO-239 connectors wired in parallel and mounted close together, side by side? 

That is, the input and output sides of the box would each have a pair of coaxial connectors wired in parallel. If I'm using RG-6 I can use the "F" connectors. If I'm using RG-6 I can use the SO-239s (one connector on each side at a time!).

Will this cause problems?
Thanks,
