“All of this is legal, excepting perhaps the paint and that’s not for sure.”
No everything you said is illegal in Texas. Nothing can be over your plate. NOTHING No covers, no plastic, no tilt nothing. It must be the raw plate mounted by bolts only to the frame or bumber, front and back , you cannot have a frame either if it covers more than 1/2” front the edge of the plate the number and 1/2 inch around them just be not only visible but in covered. You will be pulled over with valid probable cause if you violate this and God help you if your refuse the breathalyzer they will demand regardless of the time of day have anything above 0.01 BAC and they will use the subjective experience to bring you in for a blood test , you might beat the charge but you will not beat the ride to lock up. The process is the punishment. I guarantee Frisco, Plano and the Colony Texas will absolutely roast you for exactly what you think you can get away with they will take great pleasure in making the next 48 hours of your life the worst. My attorney friends make bank defending people exactly like your ideas. I have seen people taken to jail from a parking lot for not having a front plate. Oh out of state plates... How long have you been here do you have a rental even an airbnb here , have you been here for more than 4 weeks? Sure lie that is another now state jail level felony. They will pull credit card records post arrest as part of discovery bank on that and with Flock they can also just pull the records of when and how long that out of state plate has been tagged in Texas longer than 30 days you must change it and get a Texas DL too. Flock makes it easy to tag by time and place. It’s not just Dallas, Austin Houston and San Antonio use them too if you have been driving in Texas your plate is on them day in and day out. Most of the PD also have plate readers on their patrol vehicles themselves always scanning. Don’t be without insurance that’s in the state database too. I got pulled over when state farm had a glitch and it showed my insurance was lapsed it had not been 25+ years with state farm always on auto pay. Frisco PD pulled me over when it’s plate reader showed I didn’t have valid insurance it was automatic he got a alert from the system as his vehicle drove past me he slowed down and jumped behind because of that alert. What was his first question as @ 8pm it was not do you have insurance it was where are you coming from and have you had anything to drink tonight. Again probable cause they make BANK on DUI it’s what local cops live for. Wasn’t speeding and FSD was driving better than humans ever could it was the plate tagging that gave them cause.
You are, as usual, incorrect.
The only one doubtful is the paint, as noted.
