Currently, there is V1-4C51 as the V-Source reference under 内 U+5185, but there is no V-Source for 內 U+5167. 内 U+5185 and 內 U+5167 is unifiable when they are used as the components
Almost all these components used for V-Source are all 内 U+5185.

There is only one case which used the 內 U+5167.
U+225C9 𢗉 V2-7552
It’s better to accept this normalization to make the V glyphs consistent.
Maybe we should consider to modify the V2-7552 glyph for U+225C9 in future.
As Eiso points out, 内 U+5185 is more common in Vietnamese Nôm usage and we have generally, but not completely normalized the glyphs in the NomNaTong font to use this shape. We can consider further normalizations in the future. Note, though, that 內 U+5167 as a stand alone character is also used in Vietnamese and we will probably propose horizontal extension in the future.
