be prepared for a denial. As you know from your several year history of living in Bangkok on various visas and exempt entries, its time to buy the Thai Elite Visa or get a job with a work permit.
BTW...I do not recommend you fly back into Thailand. Use carefully chosen land border entry.
And any entry is the decision of the Thai Immigration Officer.
That is true regardless of your obtain I by a new Tourist visa tomorrow.
Good luck.
