Has "⿰面了" been suggested as a analogical simplification of 䩍? I was looking at: 䩍. I figured there might have been an analogical simplification suggested that looked something like: "⿰面了". Zisea doesn't offer any variant characters. Baidu offers zero results for a search of "⿰面了". Google gives two results for "⿰面了" but they're both false-positives.

I realize that 䩍 is not a very important(?) character. It was only added into Unicode in CJK Ext. A. But, it is not entirely uncommon for a CJK Ext. character to have an analogical simplification (e.g.: , CJK. C; , CJK. G).

Has "⿰面了" been suggested as a analogical simplification of 䩍? Perhaps it needs to have been published for it to gain any traction first, though.
Yes, but actually no.

Yes, because the 2.9.008 rule of the second part of the Second Stage simplifications (1977-1978) postulated simplifying 尞 to 了 wherever it occurs: 撩, 瞭, 缭, etc.

No, because all the simplification schemes are explicitly referring to popularly used characters only, and the practice was and remains to avoid overindulging in simplifications: texts where such characters can occur are probably about the character itself, and thus its original form is preferred. 䩍 (U+4A4D) is not even remotely a popular character, with its only claim of fame being the appearance in the Kāngxī Dictionary.

By the way, note that in the actual Second Stage, were it implemented, 面 is simplified into  (U+2BA51) as well (rule 1.2.009). So, ⿰了 is the actual IDS you are looking for, looking like this (http://glyphwiki.org/wiki/u2ff0-u2ba51-u4e86, just drew it):
