No, unless you account for some additional attenuation from the Brett in the bottle. So being at 1.006 I would make the assumption that there will be an additional 4-5 gravity points of further bottle refermentation with the brett. You can bottle now and figure that carb contribution into your priming calculation. Only thing is that it may take 4 months or so to become fully carbed. Also there is the slight chance you will end up on the high or low side because or the varibles. So if you can be happy with a range for a carb and be patient, then go ahead and bottle. Otherwise if just using regular bottles, you certainly risk blown bottles. That is unless you have brewed this recipe a number of times and it is fairly predictable.
Your other option is to take enough wort for three or four gravity samples. Then get it to like 85f and do a forced ferment almost to sort of predict your final gravity before the rest of the beer gets there. That will take about a month at least though.
