ER to IBD Early?

I've seen a couple posts on this topic, but they are either old (2009) or apply to post-MBA grads.

I want to know if it is possible to switch within the 2-3 years out of undergrad at a MM size bank? And if so, would the transition be easier for certain coverage/product groups?

This is assuming I do well during my time in ER, as I already have a good number of connections in different IBD groups.

Thanks.
