If by switching to the Jets means a better income... Ironically by self funding the TR you are helping the airline industry in deteriorating the conditions.
Be a CPT in the TP company that you are needed and respected. Let the Jet companies suffer from the need of pilots, let them realize how much value you are for them and let them come back with a proper invitation. At the end a job is a job... You get paid to work not the other way around.
