Usualy bad unless you have huge room and really know what you are doing.
I see you have a THX av. Why not follow almost 30 years of research on this subject?

The only way to know what is best is to test the configurations.
I asume that since you ask about fronts for rear speakers is that you want some louder booms in the back.
The best way of acheving that is multiple correct set up subs. Idealy one under each speaker and 100% perfect bass "flow" all over. However for that you need nice size room and money and then some more money

Why not get speakers that are designed as rear speakers and use the extra leftover funds from not buying big fronts for back use, to get a extra sub and experiment with?

CrazyBLUE may disagree with your thoughts.

In reality, there are two schools of thought with towers as surround.

Some feel that all 5/7 speakers being the same will truly give you a uniform sound with the tweeters all the same height and all the same timbre. These are usually also the crowd who prefers multi-channel music versus movies.

Others, like you, feel that since the surround usually doesn't have the boom, you don't need the tower, but a bookshelf or bipole/dipole speakers. These are usually the crowd who enjoys movies more than multi-channel music.

In the end, it depends on your preference. The towers may produce a fuller midrange, but that may not be what you are looking for.

If you can do an in-house demo, I would try both and keep the setup you like best.
