Hi buddy,
Wow - Tamiya's attempt at 'Zimmerit' is pretty poor and, tbh, plain lazy (imo).
It's not well defined and crisp like it should be - shame on Tamiya as this is a really expensive kit too!
I've just had my birthday and asked the parents for Dragon latest Elefant variant with moulded-on zim. Dragons latest pre-Zimmed kits are very good imo. I can't wait to start this one!

- As for you not being able to add your own Zim I'd say to you - "WOAH"!
I've only needed to do it once but on a 1/48 StuG and it wasn't that bad. At least with the Elefant you don't need to do the whole vehicle - just the parts along the hull walls and front and back. Perhaps you could add your own putty applied Zim on areas where it's easy to apply i.e. the side walls and front armour. You can use the stickers for the tricky bits and you can leave a lot of damage on it on areas that you struggle with - just paint these spots with primer red.
I reckon the side wall runs would be pretty easy. Note how high the Zim goes up the side and put masking tape on the area above where the Zim stops so it will be nice and tidy when removed or use a scalpel to tidy up the top edge. Putty it on and use a flat bladed screwdriverto make 'impressions' in vertical rows OR even better just get a proper sized toothed cog like from a radio controlled vehicle kit. Mount it on a strong paperclip and roll it down the side - it works a treat!
Before you commit to the stickers Google about making and adding your own Zim and you'll do a good job. I used WHITE Milliput but the guys on here may suggest a better putty to use.
If you've already done the stickers then no problem - just make the very best of what you have. I'm just very surprised that these stickers were the best that they could do?
Go for it! You'll be VERY surprised at how easy home made Zim is to apply. You can test it on a piece of plastic card etc first.
All the best and good luck!
