This accent is rhotic and has no trap-bath split or lot-cloth split and has flapping of intervocalic /t/.

What do you think about this proposed accent?

I think it should be cot-caught merged.

>>I think it should be cot-caught merged.<<

You do realize that (a bit) less than half of all English-speaking North Americans are cot-caught merged, much the less all English-speakers altogether, do you?

I think it has sensible suggestions. I also think it could do with plain [u:] in "suit", "lute", "chew" and "juice" though. Does it have flapping of /t/ after /n/ or /r/?

<<You do realize that (a bit) less than half of all English-speaking North Americans are cot-caught merged, much the less all English-speakers altogether, do you?>>

So? It may not be the most common thing, but that doesn't mean it's not the best way.

Is it the best way?

Some further points:

"fail", "sail", "stale" and "bail" should have [eI], since this is what's commonly used in those words in both RP and GA.

"feel" and "eel" should have [i:] for the same reason. Similarly, "pool" "tool" and "rule" belong with the [u:] words.

"bowl", "stole" and "roll" should have [7U] (or, perhaps, a rounded allophone before dark L such as [QU] or [OU]). [O@] seems a strange choice in these words.

All of these comments, of course, given the assumption that an "international accent" should stand halfway between RP and GA.

The reason why centering diphthongs were specified in these cases is that it is common in Engilsh dialects to have breaking in /i/ and /u/ followed by /l/, and it is not too uncommon for such to happen with /e/. The matter, though, is that this is really not the use of centering diphthongs but rather the syllabification of said /l/. Another note is that this is purely allophonic, so there is no reason to need to specify these separately in writing.

I think giraffe and zebra should rhyme.

There was this tall fellow called Stu
Who wasn't quite sure what to do.
When his head hit the ceiling
He had this strange feeling
Of being a giraffe in the zoo.
