I'm sure I'm not unique in replacing the often awful satellite speakers supplied with 2.1 and 5.1 systems.
In the 2.1 system in my bedroom I use my old book-shelf speakers as satellites. The system has a fixed x-over point of 125Hz which calls into question the point of the redundant ports. I could: (i) Leave well alone. (ii) Seal them. (iii) Shorten them, retuning them to a point where they are making a contribution.

Of the options presented I'd be trying sealing them. Remember that the response/phase will change. Making a fair comparison involves taking that into account and adjusting accordingly using position, and equaliser.
Do you have DSP to adjust and can you can measure the T/S parameters? If so I would calculate a QB5 alignment for them and see if that works.
