Could Russia surpass China for arms imports to Pakistan?

Assuming the SU-35 deal goes through.. it’ll mean Pakistan will operate the most advanced Flanker variant in Asia..
it also continues a trend that when given the choice, Pakistan will opt for non-Chinese alternative (and if stuck with Chinese, will insist on western modifications).

For Russia, it simply expands a market. They already sell to both Armenia and Azerbaijan, China and Vietnam, and now India and Pakistan.
and why not, the US sells F-16s to Pakistan and offered a better version to India.

Potential things in Pakistan that need replacement
T-37s with Yak-130s (although they recently got a crapload of T-38 Talons from Turkey).
Mi-28 or Ka-52s instead of Z-10s
T-90s over T-84s and MBT-2000s and 3000s
Gorshkov frigates
