Is it a good idea to have French soldiers in the German army?

Regarding the foreign soldier / colonial troops thing:
It would be cool if we had some sort of "Colonial Infantry" as a unit model that is like the opposite of guards (= weaker INF) and can only be recruited from non-accepted cultures.

Here is the situation:
1. I passed the last 3 column of political reforms during liberal agitation & springtime of nation period.
2. By the end of springtime of nation, I only managed to pass Only Landed.
3. It is now already 1979, I still cannot pass one single social reform, my upperhouse is dominated by conservative by large margin.
4. Every time I change party to National Liberal, all hell break lose on rebellion, I already have 3 Jacobin, 2 Anacho-Liberal & 1 Reactionary rebellion. Super annoying when it breaks during war time. And I can feel that the next to come is communist, making me very hesitant to change party again, but yet I want LF & limited citizenship.

What shall I do?

I think your problem is low the low overall CON.
Because of that only few people want reforms. Since no majority is supporting them, you can't pass any reforms and they will start to gain MIL and revolt over and over again.
Try to research techs that increase your overall CON gain, and reduce the number of clergymen. Try to make your pops buy luxury goods.

Apart from that, you should try to stay at weigthed wealth or similiar voting rights levels, because rich pops are usually liberal or socialist, while poor pops tend to be conservative unless socialist events drive them "red".
