Wikipedia says 16Mhz 68k available "late eighties". So possibly not 1986, though 12.5Mhz versions were definitely available (even earlier).
That said, increasing the cpu clock would not have been an easy task. In fact the 7.16Mhz is derived from NTSC video timings, and everything runs with it. You can't simply run the cpu faster (well actually there's overclocking projects for such hw which overclocks the cpu when it doesn't access the bus basically, but it doesn't make things all that much faster - remember the 68k has a total cache size of exactly 0 bytes for both data and instructions...).
So, realistically if you want it to be faster, you'd have to design everything around the faster clock, from custom chips to ram chips. Not saying it would have been impossible (possibly though only around 12Mhz 1986 (and the amiga being built around ntsc video timings would have made that difficult - even the amiga 1200 with its 68020 STILL uses such timings, just at exactly twice the frequency of the A500)), but certainly it would have been quite a different box, not just basically the same box with a faster cpu.
