No, because consonant clusters always have sheva in the middle, so
notionally there is always an alternation of consonants and vowels in a
regularly spelled Hebrew word. But there are other sequences which are
ambiguous between ending in a consonant or a vowel, notably yod
following hiriq, and vav with dagesh which may be shuruq. This gets us
back into the complex algorithm I looked at before, which can almost but
not quite disambiguate these cases but may need more processing power
than can be put into a font. Then there is Ted's point that we shouldn't
assume that all words which anyone tries to render are regularly spelled
Hebrew, some might be in other languages or have deliberate
irregularities. I guess it is for reasons like that that we have
separate final letter forms in Hebrew script, and in Arabic script
mechanisms like ZWJ to force exceptions to the shaping rules. Well,
let's not get into using ZWJ etc and instead define the additional
characters which we need.

Well, your hope is justified when there is a preceding dalet. But the
ambiguities in this case are in principle exactly the same as with vav
and holam, you need to know whether what precedes is a consonant or a
vowel. If we do want to distinguish the two positions of holam while
keeping it following the base character, the only way which doesn't land
us in a nasty mess is to define a second variant of holam.
