I assume this is can be done with avisynth as swell?

You can make interpolation to get 60p then interlace to get 60i (actually 30i, see below why*) with a script like this ;
Code:
source(25p...)
assumefps(25)
InterFrame(NewNum=60000, NewDen=1001, cores=2)#to get 59,94... fps
assumeTFF()#or ComplementParity()
separatefields()
selectevery(4,0,3)
weave()#29,97i (also called 30i and 60i)
* The term 60i is a nonsense widely spread, 30i (or 29,97i) should be used instead because the number should always refer to the framerate and not the fieldrate to avoid confusion, then the i or p is enough to tell if it's interlaced or progressive.
About 60p in 1080p : it's not officially supported by BD but I've read on another forum that a guy made a 1080p60 (or 1080p50) BD with Pinnacle Studio 17 and read it successfully on a Sony BDP-S4200.
But there is another solution that will work with more Blu-ray players : AVCHD, because AVCHD supports 50p and 60p in 1080p since 2011 (AVCHD 2.0) ;

I tested it successfully on 2 players (h264 @ 28 Mbps in 1080p50 burnt with ImgBurn on dvd+rw in AVCHD format created with TSMuxer).
