Nope, most states require either a certain percentage/number of registered voters for a party or a state-wide petition to get onto the ballot. The only 3rd party on all 50 states' ballot is the Libertarian party. The Green party is a distant 4th place, as they often need to regather signatures and new petitions every 2-4 years.
If a new party was formed for 2028, it might get enough ground in one state, not any to really sway the balance of the Electoral College.
Equally true with anything about Trump's intelligence.
