Is it possible to clone mifare mini tags by using mifare classic 1K?

I spent several days trying with no luck. I have some mifare mini tags, I know their passwords and I have dumped them. I also have some magic cards (gen 1a) and, of course, a proxmark3. I'm starting to think that maybe it's not possible and I'm just wasting my time. Should I give up? Would it be necessary a new lua script that is not written yet and some UID writable mifare mini tags that almost nobody sells? The specifications of the tags I'm trying to clone are:

7 byte UID (the first 7 bytes from block zero)
5 sectors, 20 blocks and 320 bytes (nothing new here).
SAK 0x09
ATQA 0x4400 (bytes 9 and 10 from block 0)

Thanks.

...you will need a 7b uid magic tag
...you will need to set sak/atqa to match your mini tag on your magic tag

and you should be just fine

When you say 7 byte UID magic tag...does it have to be mifare mini or would a mifare classic 1k do it?

Edit: 13.56Mhz M4k S70 7byte UID changeable Card 0 block writable Chinese Magic Card? Would "hf mf csetuid 01020304050607 4400 09" command work? UID is supposed to be 4 bytes long in csetuid command.

S70 = 4k
S50 = 1k
S20 = mini

As long as the magic tag supports changing of sak & atqa it should work with either s70 / s50

Thanks a bunch, Iceman. Looking at aliexpress I can find "13.56mhz UID Changeable MF 4k S70 NFC Card RFID Copy Clone Rewritable S70 Card" but I'm not sure if they are 7 byte UID cards or not as the sellers don't say it and having a look into https://www.nxp.com/docs/en/data-sheet/MF1S70YYX_V1.pdf I saw they can be "7-byte UID, 4-byte NUID". Where/how can I find them?
