No. If you put the bridge rectifier on the LOW voltage (primary) side of the
transformer instead of the high voltage (secondary) side all you will
achieve will be to send a heavy DC current into the primary of the
transformer, the core will saturate and you will most likely burn out the
bridge or the transformer if not both.

Aside from which the transformer ONLY works with AC flowing in the primary
and without this there will be NO output on the secondary (there may be some
induced voltage from the 100Hz or 120Hz "ripple of the unsmoothed DC flowing
in the primary but this will be AC at the ripple frequency and will almost
certainly be unsatisfactory for your purposes).

The ONLY place you can put the bridge is AFTER the transformer so that the
high voltage AC will be converted into DC, so unless your diodes can be
connected either singly or in series to give a PIV of 3 times the RMS output
voltage of your transformer they are unlikely to be of any use.
