Not to go deep into different thoughts, I would suggest a different approach than patch cords with a goal of a semi-permanent setup.
In any case, with your original question, the flow of power is not that your inverter is feeding power into the breaker panel, it is the other way around. When on inverter power and w/o the generator or shore power, there is no power at the breaker panel. So connecting one breaker to another would not make any difference. Also, each and every breaker in there already shares a common bus. In other words there is only one power input that is connected to all of the breakers (30a setup, 2 legs for 50a setups).
To be more succinct, the answer to your question is "no".
There are other options you could check into though, one is to use a separate subpanel of say 4 or less breakers that the inverter powers, or another transfer switch to the existing breaker panel similar to what you stated about the dpdt switch which would power all the breakers (you would need to turn off all that were needed to be powered) and if you do that you have to be very careful or you will overload the inverter, especially with inverters that do auto transfers (dpdt auto transfer switch builtin) and the power goes out while the A/C is running for example. Several different options for sure.
A simple option is just to run a small extension cord to an already powered inverter outlet. Just depends on how much effort you would like to put into this and the setup capabilities that you would like to have. BTW, which 2200w inverter do you have? ~CA
