Denis: coming up with a design suggestion for a distinguishable dotless iota (without alterating the distinctive 'i') was the open purpose of the bug report! ;-)
Perhaps an treatment solution to try would be some combination of the following:
* the Ubuntu Mono (curved) lower case glpyh 'i', minus the top serif.
* and/or a slightly large bowl/uptick to the tail perhaps in combination (if still needed to fill out the width),
* possibly a touch of curved oblique on the stem echoing the recent design solution for 'ν' (lowercase nu) vs. 'v' (lowercase vee); (see also 'τ' (lowercase tau))
