Question about sandhi in Pali

[Sarathi]

This is the 353rd verse of the Dhammapada:

Sabbābhibhū sabbavidūhamasmi, sabbesu dhammesu anūpalitto;

Sabbañjaho taṇhakkhaye vimutto, sayaṃ abhiññāya kamuddiseyyaṃ.

I study Sanskrit, but not Pali. The Sanskrit rendering of this passage (which is very similar) I can read without trouble, so my question concerns sandhi. The first three lines of this verse are very inspirational to me and I was considering incorporating them into a tattoo in Brahmi script. I thought about using the Sanskrit version so I could understand it more but I like the idea of using the original better. Anyway, my question is about these two words: dhammesu anūpalitto. Should there be a sandhi change here? I read some Pali sandhi guides and the way sandhi is used in Pali seems to be somewhat inconsistent compared to Sanskrit. I came away thinking that the "a" should disappear, leaving you with "dhammesunūpalitto" but I don't know if this is correct and when I count the syllables it seems that doing this leaves that line one syllable short compared to the rest of the meter. Was hoping someone could clarify.

The declension for sabbesu dhammesu is locative - literally 'in all Dhammas'. The phrase would be grammatically incorrect if only dhammesu is combined with anupālitto for the purpose of euphony. However, I think a mixed compound of all three words would retain the meaning, i.e. sabbadhammanupālitto (or maybe sabbadhammānupālitto)
