Meanwhile in Texas, each State Senate District has 940,178 people. 70,000 people in a state senate district just seems more workable.

Such a theory (this really refers to the Texas-specific 5 state theory upthread; your “any number” theory, which presumably is the same theory that applies to any State, is valid, but not unilateral like the 5-state theory) exists, but it requires starting with a dubious interpretation of the act annexing Texas, and then flatly ignoring the act admitting Texas.
The Texas House has 150 House Districts, based on the 2010 Census. Each House District has a population of around 167,637 people.
