I really like how you put so much thought into devising this interesting system. If it makes it easier for you to record or describe a game, then that’s great. However, I think its complexity might make it difficult for many to adopt. Like a lot of shorthand systems, it may come naturally to its inventor, but appear indecipherable by others. I don’t understand how one would use your system to record a whole game, but maybe you intend it as only a system for recording comments on moves in shorthand?
If an electronic device is not allowed, but pen and paper is, then I think I would prefer to use a game recording sheet (as mentioned by @Vsotvep), examples of which are available here:

However, if a recording sheet was not available and/or I was restricted to plain text, then I would try to note down the moves by their coordinates. Personally, I wouldn’t attempt to do this with the typical “A1” coordinates, since I wouldn’t be able to remember if whether Q17, P16, or something else was the top-right star point.
In the past, I’ve thought about how I would try to determine and visualize coordinates on a real board without labels, and this even led me to propose a corner-relative system, where the coordinates reflect the distance from the nearest corner, while also unambiguously distinguishing which corner. I brought it up on the LifeIn19x19 forums, which led to quite a lively discussion:

Essentially, my system would label the points on the board like this:
A1 B1 C1 D1 E1 F1 G1 H1 J1 K1 91 81 71 61 51 41 31 21 11
A2 B2 C2 D2 E2 F2 G2 H2 J2 K2 92 82 72 62 52 42 32 22 12
A3 B3 C3 D3 E3 F3 G3 H3 J3 K3 93 83 73 63 53 43 33 23 13
A4 B4 C4 D4 E4 F4 G4 H4 J4 K4 94 84 74 64 54 44 34 24 14
A5 B5 C5 D5 E5 F5 G5 H5 J5 K5 95 85 75 65 55 45 35 25 15
A6 B6 C6 D6 E6 F6 G6 H6 J6 K6 96 86 76 66 56 46 36 26 16

It is inspired by another corner-relative system, Audouard Coordinates, which was devised by Pierre Audouard to cope with his degenerative vision loss during his career as a professional go player.
