I searched all remaining k<=12 and b<=1030 up to n=25K. There were 45 k/base combos for k=8 thru 12 that needed to be searched for n=5K25K. I found the following 11 primes:
8*997^158141 9*990^230311 10*599^117751 12*593^160631 10*537^7117+1 10*827^9894+1 10*929^13064+1 10*1004^10644+1 12*600^11241+1 12*607^7582+1 12*673^7789+1 The files in post #62 have been updated accordingly.

I've included two pages in the PrimeWiki for these values:
 Riesel type  Proth type I took the data from post #62, compiled as CSV (link for download given) for all 2 ≤ k ≤ 12 and displayed all wanted values. The table columns are sortable.
