First, I'd start by asking "what is the problem you are trying to
solve?" Is this a scenario from some source? I say this because
it's Very Bad Real-World Practice _ever_ to have _all_ your IGP
routes in your EGP, or vice versa. I recognize that redistribution
scenarios to do silly things like this still are likely to appear on
the lab exam.

Second, yes, you could probably do that. IIRC, there used to be a
limit of 200 network statements under the BGP router command, but
this restriction was removed or relaxed in a fairly recent release.
Doing what you are suggesting still might not be very scalable.
