Present participle

I have a question about this root :

Number: 685
Root: ghou̯(ē)-
English meaning: to notice, pay attention
German meaning: `wahrnehmen, Rücksicht nehmen auf'
Material: Lat. faveō, -ēre, fāvī, fautum `bin gewogen, bin günstig,
schweige beim Gottesdienst'; favḗre aus *fovḗre wegen umbr. fons
`favēns', foner `faventēs' aus *fou̯enis;

Would it be possible that a form like *ghwH1-ons- or *ghw-ons- could
have existed in PIE ?
That is to say like fav-ê-ns but with -o-.

Thx
