Not at all. The 2600 is normally only capable of drawing flawless 48 pixel-wide arbitrary images with players. Wider arbitrary images require other trickery, such as flicker or external hardware assistance, and the 96x2 minikernel uses a form of flicker; here's the comment on the 96x2 minikernel from the manual...
To display a bitmap this wide, this minikernel employs a flicker technique called flickerblinds. While flickerblinds is not as objectionable to most people as regular flicker is, it can still be distracting.
Nothing easily done to do exactly that. You'd need to insert 2 color changes into very specific parts of the kernel, and it's already pretty full.
If you're not using the other player, I think if you use NUSIZ# with far copies you can make a border out of the player by positioning it at the far right border and allowing screen wrap to draw the copy in the left border position. IIRC the positioning for that technique works out right, or very close to right.
very useful clarifications.
I will try to use the second player in order to add some colors.
See you soon,
