Composite Buildings

Introduction:
After the devs revealed they would be making t6's and t7's in the spring, I was saddened for 2 reasons. One of them is that I will never be able to afford these. The second is the fact that the new tier of buildings will probably be the same as any other tier of buildings released previously; the set of troop buildings, spy buildings, and towers. My question is, why only increase the stats of the buildings, but not the type of buildings?

Actual idea:
I would like to propose a composite type of building, or a building that has both attack and spy stats. The statistics of the builds could be similar to t5 level ones or twos, such as 110k attack and defense, and 70k spy attack (or some other number.) This could be used for ebs like smoke signals or for the estoc wars, offering a bit more variability in ones build. Having it can offer a few benefits:
-build is dynamic, one could use the capability to attack varieties of builds.
- for example, if one had 2mil regular attack, 1 million spy attack with 10 composite builds, one could have 3 million attack or 1.6 spy attack. What this could mean with higher stats is a way to have a potential strength against builds despite towers- would one put up more towers to protect against composite builds or stay the same?
- a new estoc strategy?
-I don't like ebs like smoke signals. This build allows me to skim and not unload troops or spies depending on phase I'm lazy


The obvious downfall is that attacking or spying on someone with this build would decrease ones overall troop and spy strength. As a result, this would cause one to be knocked out faster in estocs than normal. (I think?)

TLDR: troop and spy builds in one build. Is the idea interesting and possibly useful or a horrible idea?
Sorry for no art or pictures, I'm too lazy
