No.
The output of the "relocated exec" directive is slightly different to
the UCD-SNMP-MIB::extTable, and is not actually a legal SMI
structure.   It is impossible to define a MIB that matches this.

That was one of the reasons behind introducing the "extend"
directive, which uses the same MIB structure for both standard
and relocatable forms.

Yes - that is possible.

You haven't said whether these are SNMPv1 traps, or SNMPv2 (or v3)
notifications.   If this is an SMIv2 MIB, then I'd suggest you define trap
OIDs of the form
    .1.3.6.1.4.1.29302.1003.0.{trap}

That is the most reliable way of defining trap OIDs, that will work
properly with both SNMPv1 and SNMPv2.
