I have patched libstdc++ to make this possible, and I did it in 3 steps.

Step 1 - Introduce 3 new template parameters

    https://github.com/healytpk/versatile_function/commit/7ac083eab3178ff57030f164de84e16779d2dc43

Step 2 - Change std::function to std::versatile::function

    https://github.com/healytpk/versatile_function/commit/fafe84a63fa1602dc7262021384a0ae334ea5b6f

Step 3 - New class std::constant_size_function

    https://github.com/healytpk/versatile_function/commit/ea4d44bcdad089bc8106220f7cd49a863d27c620

You can test it out up on GodBolt here:
