Can 6SN7 rewire pin replace 7119?
If the design use 7119 can I rewire pin of 6SN7 and used it instead of7119
Thank you

You can rewire and replace the B9A base with an IO base but totally the wrong type of valve.
A 6SN7 has totally different characteristics.

IIRC, the "super" medium μ twin triodes come only in Noval (9 pin mini) packages. FWIW, JJ's ECC99 (which is in production) is reasonably close to Philips' 7119/E182CC
As Jon says DON'T do this , it bears no logical-technical-engineering reasoning to the design reality of a circuit DESIGNED for a E182CC which in my industrial Mullard handbook is a SQ (special quality ) industrial tube .
On the other hand if you are influenced by comments of--sounds nice/smooth etc be aware that might be because of the larger inter-electrode capacitance's but that in itself has drawbacks.
90V is the plate working voltage on the E182CC as opposed to minimum of 250V on the 6SN7---notice the difference ?

Some of my amps use ECC99, I use an adapter
1Piece Gold Mini 5687 TO instead 12AU7 ECC82 tube converter adapter | eBay
to switch between 7119 and ECC99.
With the ECC99 footprint, you can also roll 12BH7 etc.
Sound-wise, IMHO 7119 is "neutral", ECC99 is more
"HIFI" and a little bit more in the frequency extremes. YMMV
