Well, you could try it. With one small correction (line 10 here), and 
effects exaggerated for demonstrations, it works just fine:

    \definefontfeature
       [effect-widen]
       [effect={width=4.2,delta=0.3}]
    \definefallbackfamily
       [archimate]
       [ss]
       [Calibri]
       [preset=range:cyrillic,
        force=yes,
        features=default]
    \definefontfamily`
         [archimate]
         [ss]
         [Calibri]
         [features={default,effect-widen}]
    \setupbodyfont[archimate]

    \starttext
       \doloopoverlist{\tf, \it, \bf, \bi}{
         \recursestring{{\russian\hyphenatedword{Николаевич}\
    \hyphenatedword{typography}}}\par}
    \stoptext

Gives:

(I don't have your fonts, but this illustrates more clearly the 
difference in handling for the two family definitions.)
