No.
There must be satisfied
z6 ( (z + k/z)6 + c1 (z + k/z)5 + c2 (z + 2/z)4 + ... ) = z12 + ... - 448z - 64
The only constant term on the left side is k6. The others are divisible by z.

Here are my calculations.

We can represent 2,1378M as y13+xy6+1,
where y=253 and x=227.

2,26L is y-x+1.

Now dividing y13+xy6+1 by y-x+1 and taking advantage of an equality x2=2y we get...

I was playing a little with this polynomial. I've managed to get an octic polynomial with somewhat smaller coeffs:
x^8 + 17 x^7 + 17 x^6 + 4*17^2 x^5 - 23*17^2 x^4 + 16*17^3 x^2 + 2 * 17^4 x + 17^4...
