In theory KTTF, as you resolved the MX, are not bound by the MX promises, if you choose. In essence, once the MX is eliminated, those promises go away. If they're 'too much', the FCC understands finances and available time can change good intentions. I have not seen a case where the FCC forced things.
I know quite a few good guys that are one person operations in Washington State, Oregon, Ohio, New Mexico, Arizona, Florida, Georgia, Kentucky, Tennessee, West Virginia and a few in Texas. They are have an attitude of making a positive impact on quality of life where they live. Needless to say, mostly it is a labor of love. One station has had zero funding, another under $500 a year and most in the $3,000 or under range in annual billing, entirely from underwriting. In a few places they are the only reliable signal in the town (if we think towns get scarce in Texas, about half of Oregon is a nice match for West Texas. I actually took a vacation or two visiting stations. In some instances there is a paper board but those names really have nothing to do with the station.
Make sure your simulcast agreement is worded correctly. I know a guy that got nailed on his: no fine but he had to spend some cash because of it. Funny the FCC thought it was fine a full power non-comm carried some of this LPFM's programming but questioned the agreement with the LPFM.
I can certainly say there are a few LPFMs in this section of Texas that are not doing things right and a couple of CPs that seem a little shady. Those are the ones that hurt all LPFM stations and bolster the rift between the full power and LPFM stations.
Continue the work to do more, but don't get in any rush. It is better to take it slow so you don't find yourself overwhelmed. In time your vision will happen. The worst you can do is to have to scale back.
