I would think that it will depend upon what type of septic system you install. I do not believe that you will have any trouble with an overdesigned conventional septic system but you would have trouble with an aerobic type of system as they work best with a steady flow and are originally sized for that flow rate.
I would make a couple of suggestions that you may wish to consider:
1) Make sure that you install an effulent filter in the tank outlet nozzle. This will insure you keep solids in the tank and not allow them to plug the drain field.
2) Look into dual leach fields with a distribution box and valve. This way you can run one field and rest one field. Switch between them annually.
Both of these suggestions will require that you do a little more maintenance but in the long run your septic system will last longer.
By the way in Texas you have to have a site soil survey made prior to a permit being issued. The survey will help guide you on what type of system(s) would be appropriate for your situation. The survey will look at many factors other than your soil type, such as seasonally high water table, size of property, location in relation to rivers, creeks, lakes, property lines, wells, etc.
If you still have questions that can't be answered you may be better off hiring a registered sanitarian or professional engineer trained in septic systems.
Good Luck
