As of version '0.29.2' there is no way to specify CRS/SRS when calling WebFeatureService_2_0_0.getfeature .
See:

def getfeature(
self,
typename=None,
filter=None,
bbox=None,
featureid=None,
featureversion=None,
propertyname=None,
maxfeatures=None,
storedQueryID=None,
storedQueryParams=None,
method="Get",
outputFormat=None,
startindex=None,
sortby=None,
):
"""Request and return feature data as a file-like object.
#TODO: NOTE: have changed property name from ['*'] to None - check the use of this in WFS 2.0
Parameters
----------
typename : list
List of typenames (string)
filter : string
XML-encoded OGC filter expression.
bbox : tuple
(left, bottom, right, top) in the feature type's coordinates == (minx, miny, maxx, maxy)
featureid : list
List of unique feature ids (string)
featureversion : string
Default is most recent feature version.
propertyname : list
List of feature property names. For Get request, '*' matches all.
For Post request, leave blank (None) to get all properties.
maxfeatures : int
Maximum number of features to be returned.
storedQueryID : string
A name identifying a prepared set available in WFS-service
storedQueryParams : dict
Variable amount of extra information sent to server related to
storedQueryID to further define the requested data
{'parameter_name': parameter_value}
method : string
Qualified name of the HTTP DCP method to use.
outputFormat: string (optional)
Requested response format of the request.
startindex: int (optional)
Start position to return feature set (paging in combination with maxfeatures)
sortby: list (optional)
List of property names whose values should be used to order
(upon presentation) the set of feature instances that
satify the query.
There are 5 different modes of use
1) typename and bbox (simple spatial query)
2) typename and filter (==query) (more expressive)
3) featureid (direct access to known features)
4) storedQueryID and optional storedQueryParams
5) filter only via Post method
Raises:
ServiceException: If there is an error during the request
Returns:
BytesIO -- Data returned from the service as a file-like object
"""
)

However both in WebFeatureService_1_1_0 and WebFeatureService_1_0_0 have the following parameter to specify SRS:

srsname: string 
             EPSG code to request the data in 

def getfeature(
self,
typename=None,
filter=None,

featureid=None,
featureversion=None,

method="Get",
startindex=None,
sortby=None,

bbox coordinates are given *always* in the east,north order
