If You Buy A 2nd, Reinstate 1st, Can You Add That To Opening Bid When Foreclosing?

Interested in buying a 2nd with the intent to foreclosure (abandoned property owner out of the picture). The 2nd position lender selling the note will not discount (actually wants $1,500 over what is owed) and the 1st has filed an NOD. The concern is that when foreclosing on the 2nd that if an investor buys us out at the Trustee's Sale, all of the money used to reinstate gets eaten by us. Can we legally add money put towards the first to the opening bid when foreclosing on the 2nd? Thanks in advance. Kurtis
