You can. World / New morph... / From Alphabetical List / 
PluggableButtonMorph. Now open a halo on one of the inner 
PluggableButtonMorphs. Open an inspector. In the evaluation pane, evaluate:

self roundButtonStyle: false.
(FontFamily promptUser:  self fontToUse familyName) ifNotNil: [ 
:fontFamily |
     self label:  '🗑' font:  (fontFamily atPointSize:  self fontToUse 
pointSize) ].

and select 'Kurinto Sans'.

Works nicely.

HTH,
