Using auto query manually

Hi,
I have recently replaced NHibernate with ormlite, my entire app stack is based on .net core webapi. I dont want yet to move to service stack services.

Is it possible to use AutoQuery manually? in my controller?
Something like:

ManualAutoQueryResult<User> res = ManualAutoQuery<User>.Execute(uriParams);

This way I will get the benefit of AutoQueryFeture inside my controllers.
Also, for using autoquery, do I need to purchase license?

Possible?
Thanks

AutoQueryFeature is a ServiceStack Plugin which only works with ServiceStack Services.
