As far as componant servicing procurement costs, the old Nighthawk is so cheap and sustainable now; certain F16, F5, F18 C130 (+ F15?) componants sub-systems were/are used in the Nighthawk because of cheaper developement costs and it is/was easier to hide from 'extremist budgeteers' 'congressional comitees'.
Although its stealth rcs capability is like an osprey to a apartment buildings B52, newer rads systems software, ground based multi inter-linked (hard networked) radars with advanced computer tech software make it more visible.
And also it has probably reached its structural and weapon hardware upgrade/developement limit.
Borrowed software system wise, it can still use some of the the latest developed componants systems from its contributing a/c (see my 1st serntence), where as the uber expensivelimited production/development project that isrealistically the F22 still has development growth potential in hardware, software, sytems and structure areas.
The real worth of the F22 and the even more problematic cheaper white elephant JSF (F-35 series, although the CTOL 'A'(?) version will end up the longest life version IMHO) are as industrytech/mech/etc R&D test/training/teaching subjects for the real 5th generation aircraft that might be operational around 2030+.
The 117 could still be usefull in some situations, certain to cover the capability gaps between current a/c, the training of Raptors development of Lightnings Too (punn intended)
But this is all my opinion based upon my flawed knowledge.
