Interesting!

Does your use of "AU" mean "gold"?
The use of "THRU" is slang, but as with Lite for Light, or Nite for Night; "THRU" is loosely acceptable these days.
OR..
The line
THE ALE GET HER THRU REAL LATE
could become;
THE ALE
LET HER
THRUM REAL LATE (THRUM=HUM)
You could use "RELATE" instead of "REGULATE" which is not correct even slang wise, since one cannot "gulate".
As for the use of "TO" twice, there is no letter "O" in laughter, so you cannot have "TO".
You could use the archaic word, "TAE" which means "TO".
Or consider it a "Lexigram Based Reading" (LBR) instead of a true Lexigram by setting the added letters off as thusly:
REGULAT[E]
T[O]
T[O]
G.U.R, I assume=GEE YOU ARE?
That is total cheating and not true to a Lexigram.
But when it is all for fun and practice, enjoy.
I do feel however that such use of acronyms or letters for word substitution (such as; B=BE/BEE. C=SEA/SEA/SI, G=GEE, I=AYE/EYE, J=JAY. K=KAY, L=EL, M=EM, P=PEA, Q=CUE, R=ARE/OUR, T=TEA.TEE, U=EWE/YOU. Y=WHY.. should be set off in brackets as are added letters. The exception being the poetic or archaic; "O'=OH".
I cannot see an easy way of turning it into a true lexigram however.
Maybe Lexigram based Readings should be called Lexies, or LBRs, and true Lexigrams be called Lexigrams.
