any suggestions?

For the regular weights, of 'Trade Gothic', maybe you could try using 'Bell Gothic' ( Cyrillic ), from ParaType, as an alternate.. ( And, maybe an alternate for 'Trade Gothic Bold Condensed', at least.: 'DIN Condensed' ( Cyrillic ), from ParaType.. )

Romesh,

Instead of ITC Weidemann, you could use Octava (ParaType), that has similar proportions and is also equipped with smallcaps:

You can also take a look at Adonis (ParaType):

Instead of Trade Gothic, you can use Bell Gothic (ParaType):

or New Letter Gothic (ParaType):
